About The Cover

Two-dimensional carbon-carbon double-quantum correlated nuclear magnetic resonance spectrum of a carbon-13 labeled protein, oxidized Anabaena 7120 ferredoxin (molecular weight 11,000). The lines represent the tracing of signals from the carbon chains of individual amino acid residues obtained with the “MADNMR” graphics program. See page 908. [B. H. Oh, W. M. Westler, P.
